## Plot
### In the Riverlands

A small territorial dispute between long-time enemies, Houses Bracken and Blackwood, who support Aegon and Rhaenyra, respectively, escalates into a deadly battle resulting in ruination and many casualties.

### In King's Landing

Helaena forgives Alicent and empathizes with the smallfolk about losing children. Criston proposes a bold plan to take Harrenhal, intending to use it as a strategic military base. As Criston is about to depart for Harrenhal with a military detachment, Gwayne Hightower, Alicent's brother, unexpectedly joins them. Aegon also wants to accompany the campaign on his dragon Sunfyre, but Lord Larys Strong diplomatically persuades him to remain in King's Landing. Aegon then appoints Larys as his Master of Whisperers.
In a brothel, a man named Ulf claims to a group of men to be a Dragonseed, a bastard of Valyrian blood, and the half-brother of the late King Viserys Targaryen and Prince Daemon. When Aegon and his retinue bring a new squire to the brothel to lose his virginity, they encounter a naked Aemond with Sylvi. Aegon mocks his brother, causing Aemond to storm off.

### At Harrenhal

Daemon arrives at Harrenhal on Caraxes and, after entering the castle, encounters Ser Simon Strong, the castellan, who immediately pledges his allegiance to Rhaenyra. Simon denounces his grand-nephew, Larys, claiming he had his own father, Lord Lyonel, and his brother, Ser Harwin, killed in the fire at Harrenhal. Later that night, an unseen force beckons Daemon to a weirwood tree. There, he experiences a vision of a young Rhaenyra sewing Jaehaerys' head back onto his decapitated body. He awakens before a cloaked woman who tells him he will die there.

### At Dragonstone and the Crownlands

Erryk and Arryk Cargyll are buried together. Rhaenys suggests to Rhaenyra that Alicent might be persuaded against war. Rhaenyra sends her youngest sons Joffrey, Aegon "the Younger", and Viserys away to the Eyrie to continue House Targaryen should the Blacks fail, with the Lady Jeyne Arryn taking Joffrey to ward. Rhaena is instructed to accompany them, but feels demotivated as she believes the reason to be her not having a dragon. She is mollified, however, when Rhaenyra entrusts four dragon eggs in her care.
En route to Harrenhal, Gwayne and a few soldiers recklessly head to a small village seeking amusement. Criston angrily races after them and rebukes them for their foolishness. Baela, patrolling the area on Moondancer, sees them and charges towards them, but they escape into a nearby forest. Baela reports this to Rhaenyra's councilors, who strongly suggest the use of dragons in the war. For her warning about Arryk, Rhaenyra rewards Mysaria with a place at court. Mysaria advises Rhaenyra on how to find Alicent in King's Landing. After reading Alicent's recent message, Rhaenyra decides to try and meet with her.

### In King's Landing, cont.

Rhaenyra and one of her guards sneak into King's Landing. Disguised as a septa, Rhaenyra approaches Alicent while she is at prayer in a sept and they discuss recent events leading to the conflict. Rhaenyra realizes that Alicent misunderstood Viserys' dying words about the Song of Ice and Fire prophecy, mistaking her son for Aegon the Conqueror. Distraught by the revelation, Alicent dismisses Rhaenyra anyway, claiming the war can no longer be avoided.

## Production

## Reception
### Ratings

In the United States, "The Burning Mill" was watched by an estimated 1.1 million viewers during its first broadcast on HBO alone on June 30, 2024. This was a 10.7% decrease from the previous episode.

### Critical response

The episode was met with highly positive critical reviews. On the review aggregator Rotten Tomatoes, the episode holds an approval rating of 91% based on 22 reviews, with an average rating of 7.7/10. The site's critical consensus says, "Underscoring the pains Rhaenyra takes to avert war, 'The Burning Mill' is an agonizing trudge towards inevitable catastrophe."
The episode received a rating of 4.75 out of 5 stars from Haley Whitmire White of TV Fanatic, and 4 out of 5 stars from Alec Bojalad of Den of Geek and James Hunt of Screen Rant. Bojalad noted that it was a "narratively chaotic" episode with a "logistically challenging ending," but praised the Battle of The Burning Mill at the beginning of the episode for keeping a strong thematic track, while Hunt declared it the best episode of the season so far. Carly Lane of Collider and Helen O'Hara of IGN both scored it 8 out of 10, with O'Hara stating that the episode "feels more like the sort of high fantasy drama we came to House of the Dragon for than the two previous episodes – and one that offers far more promise for the future." Katie Doll of CBR gave it 7 out of 10, saying that the episode "experiments with the boundaries of television in good and bad ways, resulting in a perplexing outing." Grading the episode with an "A-", The A.V. Club's Kayleigh Dray wrote in her review, "All in all, it's an excellent installment of House of the Dragon, and it builds incredibly well on the slow-burning tensions that have been exposed in the first two installments of this season."
Critics praised the performances of D'Arcy, Cooke, Smith, Glynn-Carney, Mitchell, and Campbell. Specific scenes singled out by critics included Alicent and Rhaenyra's reunion, Aemond and Aegon's brothel scene (noted for rising tensions between the brothers), the scenes in Harrenhal, as well as Baela and Moondancer's scene. The chemistry between Cooke and D'Arcy was also regarded as one of the episode's highlights. James Hunt commented, "They play off one another brilliantly, and you really get a sense of a wide range of emotions: how much they care for one another, still; their shared hurt, regret, and anger over what's happened since they last saw one another; stubbornness and ego that gets in the way of a true resolution." Additionally, critics also lauded Patel's direction, Alcock's return as young Rhaenyra in Daemon's vision, and the character development of Daemon and Aegon.
However, some aspects received criticism, specifically the pacing, a frontal sexually explicit scene, the omission of the Battle of the Burning Mill despite it being used as the episode title, and the lack of screentime for its secondary characters, especially Helaena and Rhaena.
